Test plugins with DOM full-screen API:
* Presence of plugins has no effect on request for full-screen on MacOS.
* Request for full-screen is denied when windowed plugin in current doc is present.
* Request for full-screen is denied when windowed plugin in subdocument is present.
* Request for full-screen is not denied when the only plugin present is windowless.
* Adding an existing (out-of-doc) windowed plugin to a full-screen document causes document to exit full-screen.
* Create windowed plugin and adding it to full-screen document caused exit from full-screen.
